Colder weather is coming - Install your Oil Cooler plates!
As ambient (local) weather drops below 55 degrees Fahrenheit, it's important to install Oil Cooler Winterization Plates on your oil cooler, if your plane recommends it. During the winter, your oil temperature may not increase above 180 degrees F and boil off all of the moisture in it due to the cold air flow through your cooler. Putting a winterization plate on your oil cooler restricts how much cold air can move through the cooler and allows the temperature to rise above 180 degrees F.
